[Impact of remote monitoring in home dialysis: 5-year observation results].

Dialysis (hemodialysis and peritoneal dialysis) is one of the main therapeutic alternatives for patients with end-stage renal disease. It can be provided in different settings, including the home setting. Published literature shows that home dialysis improves both survival and quality of life, while producing economic advantages. However, there are also significant barriers. Home dialysis patients often report "abandonment issues" by healthcare personnel. This work aimed at assessing the efficiency of the Doctor Plus® Nephro telemedicine system (adopted in the Nephrology Center of the P.O. G.B. Grassi di Roma-ASL Roma 3) in monitoring patient health status and improving the quality of care. From 2017 to 2022, N=26 patients were included in the analysis (mean duration of observation: 2.3 years). The analysis showed that the program was able to promptly identify possible anomalies of the vital parameters and activate a series of interventions aimed at normalizing the altered profile. During the study period, the system issued N=41,563 alerts (N=1.87 alerts per patient/day), of which N=16,325 (39.3%) were clinical and N=25,238 (60.7%) were missed measurements. These warnings ensured stabilization of the parameters, with clear benefits on patients' quality of life. A trend of improvement was reported by patients, regarding their perception of the health state (EQ-5D questionnaire; +11.1 points on the VAS scale), the number of hospital admissions (-0.43 accesses/patient in 4 months), and of working days lost (-3.6 days lost in 4 months). Therefore, Doctor Plus® Nephro represents a useful and efficient tool for home dialysis patients' management.

Basilic vein transposition versus biosynthetic prosthesis as vascular access for hemodialysis.

BACKGROUND: Vascular access (VA) complications account for a significant number of hospital admissions in dialysis and have substantial costs. A native arteriovenous fistula (AVF) cannot be successfully obtained in all patients. At our center, we established an autogenous brachial-basilic AVF (BBAVF) in the upper arm in patients with a failed forearm fistula or with superficial vessels that were unsuitable for preparing a good site for VA. In most of these patients, we resort to prosthetic materials for creating a functioning VA as the last strategy. The present study compared the outcomes of BBAVF and AV graft (AVG) in patients undergoing long-term hemodialysis in whom there was no other possibility of creating a VA. METHODS: We analyzed 57 complex patients, 27 randomized to receive AVG and 30 randomized to BBAVF, between 2002 and 2008. The Omniflow II Vascular Prosthesis (Bio Nova International Pty Ltd, North Melbourne, VIC, Australia), the latest-generation collagen-polyester composite, was used to create the prosthetic VA. Primary patency (PP) and secondary patency (SP) rates were calculated using the Kaplan-Meier test. The log-rank test was used to compare PP and SP rates of the single VA. RESULTS: Length of hospital admission time, total intervention time, and mean interval to the first venipuncture for dialysis were longer for BBAVF. In the early postoperative period, patients who received BBAVF had a complication rate similar to those who received AVG; however, patients who received AVG showed a higher rate of long-term adverse events. PP and SP rates were higher for BBAVF than for AVG, although this was not statistically significant for SP. CONCLUSIONS: Our results show that BBAVF should be the first choice in patients with a good life expectancy and who can rely on an available temporary VA. However, given the shorter time to use, AVG could be an alternative in patients with compromised clinical conditions and in whom a temporary VA is not reliable, considering that the long-term outcome may be considered beneficial regardless.

High doses of intravenous calcitriol in the treatment of severe secondary hyperparathyroidism.

BACKGROUND: In hemodialysis (HD) patients, secondary hyperparathyroidism (HPTH) is a severe common disease. Calcitriol administration has been demonstrated as an effective therapy. In this prospective study, our aim was to determine the necessary calcitriol dose required to control severe HPTH preventing hypercalcemia or hyperphosphatemia and avoiding parathyroidectomy. METHODS: Eighteen dialysis patients suffering from severe HPTH during a 12-month period received intravenous (i.v.) calcitriol pulse doses (2-8 mcg/3x/week). Multislice helical computed tomography (CT) cardiac imaging was performed to measure coronary artery calcifications. RESULTS: Fourteen patients showed an improvement (parathyroid hormone (PTH) level < 400 pcg/mL), one patient an incomplete reduction, and three patients starting from PTH levels between 1100 and 2386 pcg/mL did not appear to benefit from the therapy. After a 6-month therapy in 15/18 patients PTH levels were significantly lower (p<0.05). In a large portion of the group, as well as in the control group, coronary calcification values were high when compared to the normal range. CONCLUSIONS: According to our data, we concluded that severe HPTH could be treated successfully by i.v. calcitriol pulse doses reaching high doses (up to 8 mcg/3x/week) and for a prolonged period of time (6 months). In such cases, close monitoring is necessary to prevent hyperphosphatemia and hypercalcemia episodes.
